<h4 id="syntax">Syntax</h4>
<pre><code>[F,List] = ffrf(M,Freq,...)</code></pre>
<h4 id="input-arguments">Input arguments</h4>
<ul>
<li><p><code>M</code> [ model ] - Model object for which the frequency response function will be computed.</p></li>
<li><p><code>Freq</code> [ numeric ] - Vector of frequencies for which the response function will be computed.</p></li>
</ul>
<h4 id="output-arguments">Output arguments</h4>
<ul>
<li><p><code>F</code> [ namedmat | numeric ] - Array with frequency responses of transition variables (in rows) to measurement variables (in columns).</p></li>
<li><p><code>List</code> [ cell ] - List of transition variables in rows of the <code>F</code> matrix, and list of measurement variables in columns of the <code>F</code> matrix.</p></li>
</ul>
<h4 id="options">Options</h4>
<ul>
<li><p><code>'include='</code> [ char | cellstr | <em><code>Inf</code></em> ] - Include the effect of the listed measurement variables only; <code>Inf</code> means all measurement variables.</p></li>
<li><p><code>'exclude='</code> [ char | cellstr | <em>empty</em> ] - Remove the effect of the listed measurement variables.</p></li>
<li><p><code>'maxIter='</code> [ numeric | <em>500</em> ] - Maximum number of iteration when computing the steady-state Kalman filter.</p></li>
<li><p><code>'matrixFmt='</code> [ <em><code>'namedmat'</code></em> | <code>'plain'</code> ] - Return matrix <code>F</code> as either a <a href="../namedmat/Contents.html"><code>namedmat</code></a> object (i.e. matrix with named rows and columns) or a plain numeric array.</p></li>
<li><p><code>'select='</code> [ <em><code>@all</code></em> | char | cellstr ] - Return FFRF for selected variables only; <code>@all</code> means all variables.</p></li>
<li><p><code>'tolerance='</code> [ numeric | <em><code>1e-7</code></em> ] - Convergence tolerance when computing the steady-state Kalman filter.</p></li>
